I've spent a lot of time in the back of my truck bed. For me the answer is a simple easy up 10x10 with bug netting sides. It may not be quite as easy to set up as you want, but you just can't beat it. I love how you can lower one side to block wind or driving rain. I actually camped in the bed under the easy up before I got a canopy. Now I have the canopy for bed and gear storage, but the easy up for living space. Plus, you can leave camp to go hunting without tearing down the living space. Then just back under the edge when you get home at night. Just my take.
